This post is actually no longer visible on the announcements subreddit. It's not under "new" or "hot" sections and can only be found if you search for it within the subreddit. Not sure if it's because this announcement hit below 0 points or if the admin decided to hide the post (Please correct me if I'm wrong about that).

Edit: I was wrong. Change the default preference to not drop the thread below 0 and it shows up.
